Math Central - mathcentral.uregina.ca Math Beyond School return to top Leonardo DaVinci and the Golden Section One very famous piece, known as the Mona Lisa, painted by Leonardo Da Vinci, is drawn according to the golden ratio.  The golden ratio is 1:0.618 and has been coined golden because it is said to be aesthetically pleasing. The golden proportion can be found throughout the human body. A golden rectangle is simply a rectangle with dimensions that reflect the golden ratio.  The Mona Lisa has many golden rectangles throughout the painting.  By drawing a rectangle around her face, we can see that it is indeed golden.  If we divide that rectangle with a line drawn across her eyes, we get another golden rectangle, meaning that the proportion of her head length to her eyes is golden.  There are other golden rectangles that can be drawn on the rest of her body, like from her neck to the top of her hands.  Da Vinci created other pieces that were also drawn according to the golden ratio such as The Last Supper, Old Man, and The Vitruvian Man.  The Vitruvian Man (or Man in Action) is the drawing of a man inscribed in a circle.  The height of the man is in golden proportion from the top of his head to his navel and from his navel to the bottom of his feet. The Vitruvian Man illustrates all of the divine proportions within the human being
